Preferred Label : Idiopathic Cytopenia of Undetermined Significance;
NCIt synonyms : ICUS;
NCIt definition : Cytopenia in one or more hematopoietic cell lineages that remains unexplained following
thorough evaluation. The hematopoietic cell dysplasia is mild and does not fulfill
the criteria for myelodysplastic syndrome, but the cytopenia may be severe. There
is no evidence of clonal hematopoiesis or the variant allele frequency (VAF) is less
that 2 percent. There is no other evidence of hematologic malignancy. It may progress
to an overt myelodysplastic syndrome or other myeloid neoplasms such as acute myeloid
leukemia, myeloproliferative neoplasm, or mast cell disorder.;
